The EDG750 would have to be awesome,
-Quiet operation is a big positive for long game sessions were the drone can annoy you.
-750w of Gold Plus power is great for an SLI system i'm planning.
-Fully Modular means easy to install and manage cables, keeping your system looking clean.
-Flat Cables are stealthy and look great.
Overall a great PSU and it would be great putting together a system which uses the rest of the great products in the giveaway.
